1. What is the result of multiplying 0.15 by 3?

• A. 0.05
• B. 0.15
• C. 0.45
• D. 0.45

Correct answer: C

Rationale: The correct answer is C: 0.45. To find the result of multiplying 0.15 by 3, you simply multiply the two numbers together, which gives you 0.45. Choice A (0.05) is incorrect as it is the result of dividing 0.15 by 3 instead of multiplying. Choice B (0.15) is the original number being multiplied and not the result. Choice D (0.45) is the same as the correct answer but is repeated for redundancy.

2. What is 1500 milliliters in liters?

• A. 1.5 liters
• B. 0.15 liters
• C. 15 liters
• D. 0.015 liters

Correct answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters, making option A the correct answer. Option B, 0.15 liters, is incorrect as it would be the conversion of 150 milliliters. Option C, 15 liters, is incorrect because it would be the conversion of 15,000 milliliters. Option D, 0.015 liters, is incorrect as it would be the conversion of 15 milliliters.

3. What is the formula to convert Celsius to Fahrenheit?

• A. (C × 9/5) + 32
• B. (C × 5/9) + 32
• C. (F × 9/5) - 32
• D. (F × 5/9) - 32

Correct answer: A

Rationale: The correct formula to convert Celsius to Fahrenheit is (C × 9/5) + 32. This formula involves multiplying the Celsius temperature by 9/5 and then adding 32 to get the Fahrenheit temperature. Choice B is incorrect as it suggests dividing by 5/9 instead of multiplying by 9/5. Choices C and D are both incorrect because they involve using the Fahrenheit temperature in the calculation, which is not the correct method for converting Celsius to Fahrenheit.

4. How many milligrams are in 1 gram?

• A. 1 mg
• B. 10 mg
• C. 100 mg
• D. 1,000 mg

Correct answer: D

Rationale: The correct answer is D: 1,000 mg. This is because 1 gram is equivalent to 1,000 milligrams. To convert grams to milligrams, you multiply by 1,000. Choices A, B, and C are incorrect. Choice A (1 mg) is the smallest unit, and it would take 1,000 of these to make 1 gram. Choice B (10 mg) is also too small, as it would require 100 of these to equal 1 gram. Choice C (100 mg) is closer, but it still falls short of the correct conversion, which is 1,000 mg in 1 gram.

5. What is 0.875 as a simplified fraction?

• A. 7/8
• B. 9/10
• C. 5/6
• D. 3/4

Correct answer: A

Rationale: To convert 0.875 to a fraction, we write it as 875/1000. Then, simplify the fraction by dividing both the numerator and denominator by 125 to get 7/8, which is the simplest form of the fraction. Choice B (9/10), Choice C (5/6), and Choice D (3/4) are all incorrect because they do not represent the value of 0.875 when expressed as a fraction.
